摘要: |
In this survey, we present single-photon states of electromagnetic fields, discuss discrete measurements of a single-photon
field, show how a linear quantum system responds to a single-photon input, investigate how a coherent feedback network can
be used to manipulate the temporal pulse shape of a single-photon state, present single-photon filter and master equations,
and finally discuss the generation of Schr?dinger cat states by means of photon addition and subtraction. |
